This primer has now been updated with explanations of the construction of Reduced Median Networks, Median-Joining Networks and Minimum-Spanning Trees.

So, the primer now includes:

Median Networks

Reduced Median Networks

Median-Joining Networks

Recombination Networks

Hybridization Networks

Parsimony Trees

Minimum-Spanning Trees

These are all related to each other, and can be easily explained by looking at the distribution of the characters in a parsimony context. With the exception of NeighborNet, this covers the networks that most commonly appear in the literature.
